At the heart of a secure application design, whether it be a B2B or B2C, lies a set of core authentication features. These foundational capabilities include – stringent password policies, effective session management, and the convenience of social login options through Facebook, Google, and others. These features provide a dual function: enhancing user experience by offering familiar login methods while simultaneously upholding security measures to protect sensitive data and user identities.

In the realm of B2B SaaS applications, Authentication is the silent guardian that ensures trust and reliability in every workflow and transaction. Often overshadowed by the more visible elements, Authentication is the linchpin that quietly powers secure exchanges in the backdrop of business operations. 

B2B Authentication Landscape: What Sets it Apart?

B2B environments present a unique set of challenges for authentication systems, distinct from the individual user-focused B2C applications. B2B applications must navigate layered organizational structures (each with its own hierarchy) and necessitate tailored access controls for a diverse array of stakeholders.

B2B authentication involves complex needs such as - varying auth methods for different user types (such as employees, consultants, customers), enhanced login methods (such as SSO, multi-factor authentication, Passwordless auth), seamless separation of data and settings among organizations (multi-tenancy), data security requirements, integrations with external systems, custom workflows, access logs, and many more.

Compliance requirements, specific to B2B applications, impose additional layers of complexity. Regulatory frameworks such as GDPR, SOC 2 Type II, and industry-specific standards mandate stringent data protection measures, compelling B2B businesses to implement robust authentication protocols to safeguard sensitive information.

Beyond passwords and social logins: a Paradigm Shift in B2B Authentication

Lets dive deep into the key elements of authentication that are crucial for the sustained growth and success of B2B applications - especially when catering to enterprise customer segments.

Enhanced Authentication methods 

In the evaluation of B2B SaaS applications, enterprise customers place a premium on the authentication capabilities that align with their security requirements and operational complexities. Among these capabilities:

  • Single Sign-On (SSO) allows users to access multiple applications with a single set of credentials, streamlining the user experience while maintaining high security standards.
  • Multi-Factor Authentication (MFA) adds another layer of security by requiring users to provide two or more verification factors to gain access, significantly reducing the risk of unauthorized access. 
  • Furthermore, the emerging trend of Passwordless Authentication, which utilizes biometrics, security tokens, or SMS codes, is gaining traction for its ability to offer an enhanced security posture alongside a frictionless user experience. 

These methods collectively cater to the diverse needs of enterprise environments, ensuring both ease of use and the fortification of security measures, which are paramount in today's B2B business operations.

Admin Portal 

B2B application admins and IT teams within enterprise organizations need a comprehensive admin portal (specialized interface) to configure and manage authentication settings. Through this admin portal, IT admins can: 

  • Seamlessly set up Single Sign-On (SSO) integrations 
  • Configure Directory Synchronization to ensure alignment with their internal user databases (aka active directories)

This admin portal serves as a centralized control panel, enabling the customization of authentication methods and the enforcement of security policies in tune with the unique needs of the enterprise.

Customization 

Enterprise organizations often have diverse customization needs to align their authentication systems with their operational and branding requirements. 

  • Firstly, there is a significant emphasis on customizing the User Experience (UX) to reflect the organization's brand identity and themes. This customization extends to user interfaces, including the login boxes, admin portals, and even the content of authentication-related emails sent to users, ensuring a consistent brand experience across all touch-points. 
  • Secondly, the customization of authentication methods and workflows is critical; for example, some enterprises may require that all users authenticate via Single Sign-On (SSO) to streamline access and enhance security. 
  • Lastly, there is a need to configure events and integrate authentication workflows with external systems, such as Customer Relationship Management (CRM) platforms or Observability applications. 

Together, these customization capabilities allow enterprise organizations to tailor their authentication systems, reinforcing security while providing a branded and user-friendly experience.

Multi-tenancy and Org-first approach are core to B2B Authentication

Each enterprise organization would have varying Authentication methods, IT policies, and security settings for their users to access business applications. For a B2B application to support organization-specific auth methods and policies, the data architecture needs to be built with organization-first paradigm. 

Additionally, customer organizations would like to restrict data and settings access to their respective admins and users. B2B applications need to support multi-tenancy for Authentication and User Management - thus ensuring seamless separation of policies, settings, and data among different organizations. Multi-tenancy in Authentication allows B2B applications to quickly onboard and manage hundreds of new customer organizations and restrict access to auth-related data such as org metadata, user profiles, passwords, session info

The organization-first data modeling and multi-tenancy together form the core of B2B Authentication needs. While general-purpose solutions may offer basic user authentication capabilities, they fall short in meeting the complex needs of B2B Authentication, particularly in terms of scalability, customization, and efficiency.

  • Scalability: enables businesses to scale authentication systems effortlessly as they grow and evolve. By centralizing user management and access controls, organizations can adapt authentication policies and workflows to accommodate changing needs and requirements.
  • Customize Auth policies: offers greater flexibility and customization options, allowing businesses to tailor authentication processes to their unique requirements. From user roles and permissions to authentication methods and workflows, organizations have the freedom to design authentication systems that align with their specific needs and preferences.
  • Efficiency: By centralizing authentication processes and policies, this approach reduces complexity and administrative overhead, streamlining operations and enhancing efficiency. This centralized approach also facilitates better visibility and control over authentication activities, enabling organizations to monitor and manage access more effectively.

Deliver Enterprise Authentication: navigating your options

If you’re looking to make your Authentication enterprise-ready, here are your available options:

Build in-house

Building these Authentication capabilities internally gives your engineering team complete control of the codebase and the ability to fully customize these features. However, it comes with several major business risks:

  • Distracts your product & engineering teams: Developing these capabilities internally diverts your team’s focus and impacts your core product innovation.
  • Increases time-to-market and cost: Building these capabilities takes several quarters as well as a dedicated team of platform engineers. 
  • Deals slip away: Enterprise customers simply won’t wait for your SaaS product to catch up to the expectations they have around Authentication capabilities.

This option can be effective if you’ve secured a significant foothold in your market, face minimal threats from the competition, and manage a large engineering function with dedicated teams for developing platform capabilities.

Leverage open source frameworks

Open-source libraries enable your team to quickly launch the first version of these capabilities and test the waters. Since open-source is free, there’s no need to worry about additional software or subscription costs.

However, your team will need to learn the open-source architecture in order to build upon it and still be responsible for debugging, creating portals, maintaining security posture, hosting and managing infrastructure, scaling Auth and User management, and other upgrades.

Time to market seems quicker with open-source. However, they’re not built for specific, complex B2B needs. Your engineering team will need to understand their architecture, dig into their codebase, and customize them to fit your unique Auth needs and user management workflows. This defeats the purpose of using open-source tools in the first place.

Use a B2B-first authentication provider.

Transitioning into the growth stage, SaaS companies face the dual challenge of strengthening their core product and expanding to the enterprise segment. Regardless of where your company is in its growth journey, developing these enterprise capabilities internally diverts your engineering team’s focus and impacts your core product’s innovation.

In the last few years, modern platforms have given engineering teams the flexibility and freedom  to focus on their core SaaS product and not be burdened by the overhead of building additional capabilities. Many engineering teams today use purpose-built products such as Twilio for communications API, Sendgrid for email API, and Sentry for app monitoring. 

Similarly, B2B SaaS companies would benefit from third-party products that offer enterprise capabilities such as authentication, user management, authorization, audit logs, feature flagging, and more. For example, a SaaS-first authentication platform would: 

  • Significantly reduce your time-to-market with pre-built authentication and user management components
  • Solve enterprise use cases such as single sign-on, admin portals for config, pre-built login box, customization options, CRM integrations, and analytics tools
  • Reduce the burden on your product and engineering team by allowing them to focus on building your core SaaS product

While your team will still need to spend some time learning a new tool, you’ll benefit from a multitude of pre-built capabilities, reduced engineering costs, and more peace of mind with built-in security and integrations.

Consider quickly implementing enterprise features with an external product that’s prebuilt for B2B Auth, User Management needs. While your team will still need to spend some time learning a new tool, you’ll benefit from faster time-to-market, pre-built authentication capabilities, customer portals, reduced engineering costs, and more peace of mind with security and integrations taken care of.

Conclusion

It is time to reevaluate your Authentication strategy within your B2B SaaS application. The build vs. buy question is not only a technical decision but also a strategic imperative that can shape your growth into the enterprise segment.

The fact remains that using a third-party product built for SaaS products accelerates your time-to-market and allows your engineering team to focus you on your core product with minimal resources.

We encourage you to engage in meaningful discussions and explore your authentication strategies.
